FLYING YOUR CESSNA 170

Selecng a Flying Site
Selecng a ying site is crical to a successful ight. Airplanes
require a lot more room than other R/C products, therefore, a
neighborhood or parking lot is not recommended. A local AMA eld
is the best locaon for ying your Cessna 170. If no AMA eld is
available in your area, a large open eld with short grass and
generous overy area is the best candidate. Know your overy area.
Ensure that there are no houses, playgrounds, people or other
buildings that may be damaged if the airplane were to crash.
Takeo
Taxi or place the aircra on the runway centerline, with the nose
pointed into the wind. Select Flight Mode 2, with the aps in the up
posion for the rst ight. Set throle trim so that the motor spins
at it's lowest RPM without stopping. Smoothly advance the throle
to full while maintaining direconal control with the rudder and
slight back pressure on the elevator. The airplane should li o
smoothly before the throle is fully open. Fly in Flight Mode 2 unl
the aircra is fully trimmed (see special trimming instrucons), and
you are comfortable with it's handling, then explore the other
modes as desired.
Flying
Altude is your friend on the rst ight. Briskly climb to a safe
altude and trim the airplane. The airplane should y straight and
level at 2/3 power (depending on baery pack voltage selecon),
with no input from the scks. Try some basic maneuvers, and slowly
progress into the airplane's ight envelope as you become more
comfortable with the airplane's ight qualies and perfect your
setup. Note: if at any me, such as aer gain adjustments, you
experience unexpected control system inputs or oscillaons, switch
to Mode 1, and land and troubleshoot the issue. (Mode 1 turns the
sensor inputs o with default programming)
Trimming
The rst several ights on your Cessna 170 should be dedicated to
trimming and setup. Fly the airplane at 2/3 power in Flight Mode 2
and trim for level ight. Land, adjust linkages and return the trim to
zero, and y again. Repeat unl the airplane ies hands o, straight
and level. Transmier trim or sub-trim will cause trim shis when
dierent ight modes are selected. To eliminate this trim shi, you
can mechanically trim the model, or you can complete and Aura
"Quick Trim".
Aura Quick Trim
The Aura 8 features a Quick Trim Mode that eliminates the need
for mechanical linkage adjustments during test ights. Aura will
learn the trim values from your transmier, and apply them to the
control surfaces at power up when enabling quick trim mode.

USE CAUTION WHEN FLYING YOUR CESSNA 170 IN FLIGHT
MODE 3 AT HIGH AIRSPEEDS. DOING SO CAN INDUCE CONTROL
SURFACE OSCILLATIONS AND MAY CAUSE A CRASH.
Landing
Be mindful of your ight me and allow adequate baery reserve
for a couple of landing aempts, if necessary, on the rst few
ights. For the rst few landings, land with the aps in the up
posion. Select Flight Mode 2 and slow the airplane and align with
the runway, into the wind. The airplane should descend smoothly
in this conguraon with proper airspeed. Once you are close to
the ground, gradually close the throle fully and begin to smoothly
apply up elevator as required to arrest descent and the airplane
should gently touch down with a short roll out.
NOTE:
Quick Trim can also be used BEFORE ying to make
small changes to center the control surfaces before
ight.
Fly the airplane in Flight Mode 2. Trim the aircra with the
transmier and land. DO NOT CHANGE FLIGHT MODES.
Power o the Aura. Insert a bind plug into Aura Port S3 (you
will need to remove the servo lead that is currently in S3).
Check the transmier is on and repower the Aura.
Wait 5 seconds for the Aura to completely inialize. Conrm
Quick Trim mode is acve by checking the Blue LED is slowly
ashing.
Remove the bind plug from Aura Port S3, and re-install the
servo that was previously removed into S3. Removing the bind
plug stores the current trims in the Aura. The Blue LED will
ash quickly aer control surface trim values are store. While
the trim values are stored in Aura, they are not applied to the
control surface(s) unl the Aura is repowered.
Remove power from the Aura and center all control surface
trims on the transmier.
Repower the Aura. The control surfaces should be unchanged
even though the trim has been centered on the Transmier.
Switch between other Flight Modes to ensure you do not see
any changes in trim.
NOTE:
QUICK TRIM MAY BE REPEATED AS NEEDED FOR
FINE TUNING, OR IF CHANGES TO THE AIRCRAFT
ARE MADE.
ENSURE AILERON/ELEVATOR/RUDDER SUB-TRIMS
ARE ZERO BEFORE FLYING FOR QUICK TRIM
PROCESS
QUICK TRIM IS NOT AVAILABLE TO PWM
CONNECTION USERS. IF USING A PWM
CONNECTION TYPE, YOU WILL NEED TO
MECHANICALLY TRIM THE MODEL
